Appearance
Function
The OPCOM3500E-4EOS-4FX is a 4-way optical interface EOS tributary card on the
iTN2100, and it supports two working mode: EOS and ESW.
Provide four 100 Mbit/s Ethernet optical interfaces.
Support two working modes: EOS and ESW.
In EOS mode, it maps Ethernet services from the front panel to SDH signals, transmit
them to the aggregation cards for aggregation and transmission to the SDH network.
In ESW mode, it aggregates Ethernet services from the front panel, transmits them to the
switching card for uplink transmission of them through the switching card.
Support assignment of four ways of Ethernet services in bandwidth of N×VC12 for
virtual cascading, and then transmit them to the SDH network.
Support four VCGs at most.
Support two Ethernet encapsulation modes: GFP and LAPS.
Support VCAT and LCAS.
Support storm control over broadcast messages, unknown multicast messages, and DLF
messages.
Support interface isolation protection.
Support interface aggregation.
Support QoS and determine four output queues by priority.
Support 802.1Q VLAN and support 4K concurrent VLANs.
Support QinQ.
Support 8k MAC addresses and 30 static MAC addresses.
Support enabling or disabling MAC address learning based on interfaces.
Support configurable aging time ranging from 0s to 3825s. By default, it is 300s.
Support interface-based non-linear rate limiting ranging from 62 Kbit/s to 100 Mbit/s.
Support transparently transmitting BPDU, LACP, and 802.1x management frames.
Support NMS for remote transceivers.
Support message forwarding control.
Support interface access list.
Support limit on the number of MAC addresses to be learnt.
Support adding MAC addresses to the TRUNK group.
Support QoS priority overwriting.
Support interface discarding mode.
Support QoS based on DSCP.
Support bidirectional rate limiting.
Support hot swapping.
